AI Technical Summary

Technical Problem

Delivering high-quality volumetric video streaming to resource-constrained mobile devices is challenging due to high bandwidth requirements and computational overhead, leading to unacceptably long stalls and insufficient decoding performance, even with advanced compression techniques.

Method used

A network-based proxy transcodes volumetric video streams into 2D pixel-based streams and provides reduced resolution versions, leveraging GPUs and machine learning algorithms to predict viewports and optimize content delivery, offloading computational demands from mobile devices.

Benefits of technology

This approach significantly improves decoding performance and reduces bandwidth consumption, enabling viewer-acceptable frame rates and extending battery life, while accommodating diverse device capabilities and network conditions.

Abstract

A network processing system obtains a viewport of a client device for volumetric video and a two-dimensional (2D) subframe of a frame of volumetric video is obtained associated with the viewport. Viewports may be obtained from the client device or be predicted. 2D subframes and reduced resolution versions of frames can be transmitted to the client device. A client device may request volumetric video from the network processing system and provides a viewport to the network processing system. The client device may obtain from the network processing system reduced resolution versions of volumetric video frames and 2D subframes in accordance with the viewport. The client device may determine whether a current viewport matches the viewport associated with the obtained 2D subframe and provides a display based on either that subframe (upon a match) or a 2D perspective of the reduced resolution frame associated with the current viewport (if no match).
